Hello all, I have been using HM8012 for several years but suddenly the OFF indicator appeared on the screen. Is there any opinion on this problem? |

There seems to be a problem with the Cal-EEProm 93C46. Reject it and try to switch on. Best regards Frank |
| giannisv:
Dear Frank, Fisrt of all thank you for answer but the eeprom 93c46 in a socket it's easy to removed and appeared on display CAL E (calibration error), the problem remains. Best Regards, Giannis |

You can find the service manual here: https://sm5cbw.se/hameg/hm80/hm8012-serv.pdf The display of 'OFF' is not mentioned in it and i never saw it on my 3 units. So i have no further idea, what happened to your unit. Best regards Frank |

Dear Frank, You were absolutely right as soon as I replaced the eeprom 93c46 it works and you need calibration. Thank you very much Giannis |
